Wireless Device Regrouping via Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for grouping wireless devices onto a common channel, such as in emergency situations, require manual intervention by a network manager to switch devices, which is inefficient and prone to errors, especially in dynamic environments.
Innovation Solution
A method that automatically switches wireless devices to a common channel by determining the proximity of other devices to an initiator device using GPS coordinates, with a radio control manager broadcasting location information and sending instructions for devices within a predetermined distance to switch to the common channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual regrouping by network manager is used, then control precision is maintained, but productivity decreases and time consumption increases
Solution Approach 1:
The system enables wireless devices to automatically perform regrouping operations without manual intervention. The initiator device broadcasts its location, peer devices automatically determine proximity using GPS coordinates, and the radio control manager automatically sends switching instructions to devices within the predetermined distance, eliminating the need for manual network manager intervention.
Solution Approach 2:
The patent replaces the manual mechanical process of network manager intervention with an automated electronic system. GPS coordinates and automatic distance calculation substitute for manual identification of surrounding peers, while automated broadcasting and instruction sending replace manual command transmission.
2Loss of time
If manual identification of surrounding peers is required, then accuracy is maintained, but time consumption increases
Solution Approach 1:
The system pre-establishes GPS location capabilities and automatic distance calculation mechanisms before regrouping is needed. When a regrouping event occurs, the initiator device immediately broadcasts its location, and peer devices can instantly calculate distances and determine proximity without manual identification processes.
Solution Approach 2:
Automatic electronic distance calculation using GPS coordinates replaces the manual process of identifying surrounding peers. The radio control manager automatically determines which devices are within the predetermined distance and sends switching instructions without human intervention.
3Ease of operation
If manual switching of wireless devices is performed, then control precision is maintained, but ease of operation decreases
Solution Approach 1:
Wireless devices automatically perform the switching operation based on their predetermined proximity to the initiator device. The system handles the complex switching logic automatically, presenting a simple user experience where devices simply need to be within the predetermined distance for automatic regrouping to occur.
4Reliability
If automatic regrouping based on proximity is implemented, then productivity increases, but reliability may decrease due to lack of human verification
Solution Approach 1:
The system incorporates feedback mechanisms where peer devices respond to location broadcasts with their own GPS coordinates, allowing the radio control manager to verify distances and confirm which devices should be switched to the common channel, ensuring accuracy while maintaining automation.
